Specifically, this.

Back in march I briefly met Pat Coyle of the Indianapolis Colts at South by Southwest. We caught up by phone a couple weeks later. The Colts are building a social networking platform for Colts fans that will include a blog by popular coach and Super Bowl winner Tony Dungy.

Sports is a natural for social networking - the passion of NFL fans is almost bottomless. They eventually want to roll this out across the entire league. Imagine all the "smack talk" that will go on between fans of different teams! This dynamic is essentially the reason talk radio succeeds, so I believe it will be a huge success.
